Definitions
- Angular gear are needed when a rotating Movement be implemented in a different rotating movement should, with the axes of rotation at an angle to each other. Areas of application for this are machine tools, packaging machines and the same. There are different Requirements for accuracy with which the Angular movement of the output shaft of the angular movement of Input shaft follows.
- the axes of the Waves are adjusted to each other very precisely and this Retain setting for a long time. Especially must be the theoretical angle between the waves, the Calculation of the tooth geometry is the basis, also exactly match the actual angle.
- the main body in which generally the output shaft and housed both gears of the angular gear are, as well as for the auxiliary or side housing, in which the input shaft is rotatably mounted.
- WO 93/22584 is accordingly an angle gear known that consists of two housing parts.
- a housing part is a section of an extruded profile with longitudinally molded T-slots for attachment of the angular gear on a device. Through this housing part passes through a hole that works on both ends is to contact shoulders for deep groove ball bearings for To produce storage of the output shaft.
- the output shaft itself consists of a tubular axis, to the one-piece a bevel gear is formed.
- the meshing pinion is non-rotatably mounted on a shaft, which is rotatably mounted in a second housing part.
- the second housing part is screwed to the first housing part.
- the new construction is based on the knowledge that extrusions today with such accuracy can be produced that the required tolerances for angular gear can be easily adhered to without require extensive machining work.
- the housing is made of a Section of an extruded profile produced so that the main construction and fasteners for the transmission already be specified during extrusion, such as the interior, in which the output shaft is stored as well as the required grooves for Attach the angle gear. It is usually enough when the bearing seats in the extrusion section, for example reworked without cutting by rolling or rolling be the required fit for receiving the bearings to achieve. Occasionally, the fit can also be through Fine boring or spindling be generated. Apart from a revision of the front pages and a training of snap ring grooves it is only required the lateral To attach bore on the second housing part flanged and through which the input shaft in the protrudes first housing part.
- the interior of the first housing part over most of its longitudinal extent cylindrical with constant diameter.
- the first housing part of a section of a Extruded profiles it has seen over its length parallel to the longitudinal extent of the interior a constant Cross section resulting from the cross section of the extruded profile results.
- the cross section of the housing seen at right angles to the Longitudinal axis of the interior is substantially square. This also avoids unnecessary waste of material.
- the first housing part is at least on one side just to simplify the attachment of the second housing part.
- the first housing part contains at least an undercut groove, e.g. a T-groove that extends on the outside of the first housing part and in the direction parallel to the longitudinal axis of the interior runs.
- an undercut groove e.g. a T-groove that extends on the outside of the first housing part and in the direction parallel to the longitudinal axis of the interior runs.
- the first shaft is mounted by means of deep groove ball bearings. hereby unnecessary complicated adjustment measures and the far from each other deep groove ball bearings are without further capable without shortening the life possibly to withstand occurring unilateral tilting forces. Furthermore they can with additional design additional seals make redundant.
- bevel gear of the first shaft is a tubular Has extension with which it frictionally on the first shaft sitting, will be profile changes of the gearing avoided, especially when the bevel gear on the Wave has shrunk. Diameter changes duringshrinking can not be transferred to the gearing become.
- a particularly space-saving arrangement results, when the first shaft with the help of the tubular extension is stored in an associated warehouse.
- the first Wave is a hollow shaft.
- At least one end contains mounting holes. These mounting holes can be used as cylindrical cavities already incorporated into the extruded profile
- the passport is from a Outside bearing ring of a rolling bearing formed, with the help of the second shaft of the angular gear is mounted.
- This Rolling bearing is advantageously a tapered roller bearing.
- the bevel gear can be both straight and curved be.
- the bevel gear of the second shaft can be a pinion and the axes of the two waves can be both in lie on a common plane as well as offset against each other be.
- angle gear 1 is set from a first or main body part 2 and a second Housing part 3 together.
- the first housing part 1 is about cuboid or cube-shaped and we from four side walls 4, 5, 6 and 7 and two end walls 8 and 9 limited.
- T-slots are respectively two from the front page 8 to the front page 9 reaching T-slots, and also includes each of the end faces 8 and 9th four threaded holes 12 each, in the area of the corners as shown attached.
- the axes of the T-slots 11 as well the axes of the threaded holes 12 are parallel to each other and parallel to an axis of the housing part 2, the on the front pages 8 and 9 is vertical.
- the second one-piece housing part 3 flanged On the side wall 7 is the second one-piece housing part 3 flanged, made up of a cylindrical Section 13 and a radially projecting flange 14 composed.
- the flange 14 In the flange 14 are a total of four Stepped bores 15 included in which mounting screws 16 sit in corresponding threaded holes in the Side wall 7 are screwed to the second housing part 3 hold on the side wall 7.
- the first housing part 2 whose inner shape is from Fig. 2, is a section of an extruded profile for example, made of light metal.
- the extrusion direction is parallel to the T-grooves 11, so this already be formed in the manufacture of the extruded profile with.
- the core holes of the threaded holes 12 can in producing the extruded profile of which the housing part 2 is cut to length, with molded.
- the housing part 2 recognize leaves an interior 18 in the form of a cylindrical Through hole, which is substantially without cross-sectional change from the front side 8 to the front side 9 enough. Also, this through hole 18 is already in the Extruded profile containing, produced as a hollow profile becomes.
- the cross-section of the extruded profile is the view on the front 8 or 9.
- the interior 18 contains two pierced snap-ring grooves 19 and 21. They serve as axial securing for two to the center of the housing arranged deep groove ball bearings 22 and 23, whose Outer bearing ring respectively directly in the cylindrical Interior 18 sits.
- the deep groove ball bearings are at least sealed on one side to the outside and permanently lubricated. Further shaft seals are not available.
- the bearing seats of the two deep groove ball bearings 22 and 23 in the interior 18 are calibrated for example by rolling and solidified at the same time. Between each deep groove ball bearing 22 and 23 and the associated snap ring 24 and 25 is still sitting in each case a shim 26th
- the shaft 27 carries next to the end face 8 a radial shoulder 28 with which they are on the deep groove ball bearing 22nd supported.
- the opposite end of the shaft 27 is something tapers and frictionally carries a bevel gear 29.
- Das Bevel gear 29 is provided with a tubular extension 31, on a tapered portion 32 of the shaft 27th has shrunk.
- the cylindrical outside of the tubular Extension 31 forms the seat for the second deep groove ball bearing 23 and also represents the back of the bevel gear 29 is a contact shoulder 33, which is against the deep groove ball bearing 23 is supported. Due to the tubular Extension 31 will be profile changes of the gearing avoided, which arise when the tubular extension 31st shrunk on the shaft 27.
- the second housing part 3 essentially serves the Storage of a pinion shaft 34, the inside of her in the housing lying end provided with a pinion 35 in one piece is that meshes with the bevel gear 29.
- the pinion shaft 34 For storage of the pinion shaft 34 includes the second Housing part 3 a stepped bore 36, the axis at right angles on the axis of the interior 18 extends.
- the axes are in a common plane, as far as they are concerned normal bevel gear is. But you can also compete against each other be offset in height when the pinion 35 together forms a hypoid gear with the bevel gear 29.
- the stepped bore 36 has a portion 37 with a larger Diameter up, at a plane annular shoulder 38 ends. This ring shoulder serves as a seat for a tapered roller bearing 39th
- the first housing part 2 is adjacent, goes the stepped bore 36 into a short turn 44 over that on one shoulder 45 ends.
- the recess 44 has the same diameter as an aligned lateral bore 46, which is of the Side wall 7 extends into the interior 18.
- an aligned lateral bore 46 which is of the Side wall 7 extends into the interior 18.
- the outer bearing ring serves the tapered roller bearing 47 at the same time as a fitting sleeve, about the first and the second housing part 2, 3 in the correct position to fix each other, with the decentering Shearing forces are not transmitted via the screws 16 have to. It can be in this way a very high accuracy of fit achieve.
- the two tapered roller bearings 39 and 47 are in O arrangement built-in.
- the internal tapered roller bearing 47 with a larger diameter lies with its inner bearing ring a shoulder 48 of the pinion shaft 34 at.
